Description

Technical Field

[0001] This application relates to the field of sunshades, and particularly to a storage limiting structure for a car sunshade. Background Art

[0002] Car sunshades are mainly used to block direct sunlight into the car, and they can effectively reduce the temperature inside the car. In the hot summer, the sun exposure will cause the temperature inside the car to rise rapidly. Using a sunshade can reduce the entry of sunlight heat and keep the environment inside the car relatively cool.

[0003] Most car sunshades are folded to reduce the occupied area after storage. However, due to the bumps during the driving of the car, the folded sunshade is affected by vibrations and cannot maintain a relatively stable bundled state, thus affecting the driver's line of sight and causing safety accidents.

[0004] In response to this, we propose a storage limiting structure for a car sunshade to solve the above problems. Utility Model Content

[0005] The purpose of this application is to stably fix the stored sunshade and effectively avoid the situation of its dispersion. Compared with the prior art, a storage limiting structure for a car sunshade is provided, which includes a base. The base is rotatably connected with a cover plate. A transverse telescopic component is installed inside the cover plate. A longitudinal telescopic component is installed on the side wall of the transverse telescopic component. The upper end of the longitudinal telescopic component is fixedly connected with a support component. A curtain is fixedly connected inside the transverse telescopic component. The upper end of the curtain is fixedly connected with the support component. A limiting component is fixedly connected to the side wall of the transverse telescopic component close to the base. The limiting component includes a fixed block fixedly connected to the side wall of the base. The fixed block is rotatably connected with a buckle component. The folded curtain is pressed and limited by the buckle component, effectively avoiding the situation of the curtain being scattered due to the bumps during the driving of the car and improving the practicability of the sunshade.

[0006] Further, the buckle component includes a rotating block connected to the fixed block through a hinge. A reserved groove is opened in the middle of the rotating block. A blocking rod is slidably connected inside the reserved groove. The blocking rod includes a sliding section and a limiting section. A plurality of wedge-shaped grooves are opened on the side wall of the sliding section away from the fixed block. Limiting grooves corresponding to the positions of the wedge-shaped grooves are opened on the inner wall of the reserved groove. A limiting wedge is slidably connected inside the limiting groove. One end of the limiting wedge away from the rotating block is fixedly connected with a sliding rod. The sliding rod penetrates through the limiting groove and extends to the outside. The sliding rod is slidably connected to the rotating block. The blocking rod can freely slide in the reserved groove to adjust the pressing degree of the blocking rod to adapt to curtain of different thicknesses. The limiting wedge is pushed along the limiting groove by the sliding rod, so that the limiting wedge can be stably inserted into the wedge-shaped groove to limit the position of the blocking rod, which can further improve the limiting ability of the curtain.

[0007] Further, a first spring is sleeved on the outer wall of the sliding rod. The two ends of the first spring are respectively connected to the limiting wedge and the side wall of the limiting groove. A pull ring is rotatably connected to the far end of the sliding rod. By using the extrusion force of the first spring on the sliding rod, the limiting wedge can be automatically inserted into the limiting groove.

[0008] Further, a limiting block is arranged at the lower end of the sliding section. The limiting block can prevent the blocking rod from sliding out of the reserved groove.

[0009] Further, a stable extrusion assembly is fixedly connected to the lower wall of the limiting section near one end of the rotating block. By using the stable extrusion assembly, the stability of the limiting of the curtain can be improved, and at the same time, the damage to the curtain is reduced.

[0010] Further, the stable extrusion assembly includes a compression ring capsule. Both the upper and lower ends of the compression ring capsule are hermetically connected with baffles. The lower baffle is communicated with an expansion capsule through a connecting pipe. The upper and lower baffles are elastically connected by a second spring. The expansion capsule remains in a deflated state under normal conditions. When the stable extrusion assembly presses the curtain downward, the compression ring capsule conveys the air inside to the expansion capsule through the connecting pipe. The inflated expansion capsule can cover the curtain in the contact range in a large area, providing a larger contact area.

[0011] Compared with the prior art, the advantages of this application are as follows:

[0012] 1. By using the buckle assembly to tightly limit the folded curtain, the situation that the curtain is scattered due to the bumps during the driving of the vehicle is effectively avoided, and the practicability of the sunshade curtain is improved.

[0013] 2. By using the sliding rod to push the limiting wedge to slide along the limiting groove, the limiting wedge can be stably inserted into the wedge-shaped groove, thereby restricting the position of the blocking rod, and the limiting ability of the curtain can be further improved.

[0014] 3. The expansion capsule remains in a deflated state under normal conditions. When the stable extrusion assembly presses the curtain downward, the compression ring capsule conveys the air inside to the expansion capsule through the connecting pipe. The inflated expansion capsule can cover the curtain in the contact range in a large area, providing a larger contact area, and thus reducing the damage caused by the extrusion of the curtain.

[0025] Embodiment 1:

[0026] The present utility model provides a storage limit structure for an automotive sunshade. Please refer to Figures 1-3, including a base 1, the base 1 is rotatably connected with a cover plate, a transverse telescopic component 3 is installed inside the cover plate, a longitudinal telescopic component 4 is installed on the side wall of the transverse telescopic component 3, the upper end of the longitudinal telescopic component 4 is fixedly connected with a support component 5, a curtain 2 is fixedly connected inside the transverse telescopic component 3, the upper end of the curtain 2 is fixedly connected with the support component 5, and a limiting component 6 is fixedly connected to the side wall of the transverse telescopic component 3 close to the base 1. The limiting component 6 includes a fixed block 7 fixedly connected to the side wall of the base 1, and a buckle component is rotatably connected to the fixed block 7.

[0027] Specifically, please refer to Figure 5 , when the curtain 2 is not needed, the longitudinal telescopic component 4 is used to fold the curtain 2 and store it inside the transverse telescopic component 3, and the folded curtain 2 is pressed and limited by the buckle component, effectively avoiding the situation of the curtain 2 being scattered due to the bumps during the driving of the vehicle, improving the practicality of the sunshade. The buckle component here can be connected by means of an electric rotating shaft, a hinge, etc.

[0028] Embodiment 2:

[0029] The utility model provides a storage and limiting structure for an automobile sunshade. Please refer to Figures 3-4 , the buckle component includes a rotating block 8 connected to the fixed block 7 through a hinge. A reserved slot 81 is opened in the middle of the rotating block 8. A blocking rod 9 is slidably connected inside the reserved slot 81. The blocking rod 9 includes a sliding section and a limiting section. A plurality of wedge-shaped grooves 91 are opened on the side wall of the sliding section away from the fixed block 7. Limiting grooves corresponding to the positions of the wedge-shaped grooves 91 are opened on the inner wall of the reserved slot 81. A limiting wedge 84 is slidably connected inside the limiting groove. One end of the limiting wedge 84 away from the rotating block 8 is fixedly connected with a sliding rod 82. The sliding rod 82 penetrates through the limiting groove and extends to the outside. The sliding rod 82 is slidably connected to the rotating block 8.

[0030] Specifically, the blocking rod 9 can freely slide in the reserved slot 81 to adjust the pressing degree of the blocking rod 9 to adapt to sunshades 2 of different thicknesses. The sliding rod 82 is used to push the limiting wedge 84 to slide along the limiting groove, so that the limiting wedge 84 can be stably inserted into the wedge-shaped groove 91, thereby restricting the position of the blocking rod 9, which can further improve the limiting ability of the curtain 2.

[0031] A first spring 83 is sleeved on the outer wall of the sliding rod 82. Two ends of the first spring 83 are respectively connected to the limiting wedge 84 and the side wall of the limiting groove. A pull ring is rotatably connected to one end of the sliding rod 82 away from the 8.

[0032] Specifically, the extrusion force of the first spring 83 on the sliding rod 82 can be used to realize the automatic insertion of the limiting wedge 84 into the limiting groove. When the limit needs to be released, only the pull ring needs to be pulled to overcome the elastic force of the first spring 83 so that the sliding rod 82 drives the limiting wedge 84 to slide out of the wedge-shaped groove 91.

[0033] A limiting block is provided at the lower end of the sliding section, and the limiting block can prevent the blocking rod 9 from sliding out of the reserved groove 81.

[0034] A stable extrusion assembly 92 is fixedly connected to the lower wall of one end of the limiting section close to the rotating block 8. The stable extrusion assembly 92 can be used to improve the stability of the limit on the curtain 2 and reduce the damage to the curtain 2 at the same time.

[0036] The utility model provides a storage limiting structure for an automobile sunshade curtain. Please refer to Figures 4-5 , the stable extrusion assembly 92 includes a compression ring bag 921. Both the upper and lower ends of the compression ring bag 921 are hermetically connected with baffles. The lower baffle is communicated with an expansion bag 923 through a connecting pipe, and the upper and lower baffles are elastically connected through a second spring 922.

[0037] Specifically, by using the extrusion of the second spring 922 on the upper and lower baffles, the compression ring bag 921 sucks out the air inside the expansion bag 923. The expansion bag 923 remains in a deflated state under normal conditions. When the stable extrusion assembly 92 presses down on the curtain 2, the second spring 922 is compressed. At the same time, the compression ring bag 921 conveys the air inside to the expansion bag 923 through the connecting pipe. The inflated expansion bag 923 can cover a large range of the contact range of the curtain 2, providing a larger contact area, thereby reducing the damage caused by squeezing the curtain 2. Secondly, the stability of the curtain 2 is effectively improved.

[0038] The above is only the best implementation mode adopted by this application in combination with the current actual needs, but the protection scope of this application is not limited thereto.
